The US National Security Agency is looking for someone with access to their data very, very intensely.

The Guardian reporter Glenn Greenwald has published a third top-secret NSA document in less than 48 hours. The 18-page document is a presidential directive regarding "Offensive Cyber Effects Operations," which can "offer unique and unconventional capabilities to advance US national objectives around the world with little or no warning to the adversary." The effects of such approaches "rang[e] from subtle to severely damaging."

The document orders various government agencies to prepare for offensive cyberwarfare operations and says the government will "identify targets of national importance." The article quotes an intelligence source with knowledge of NSA programs as saying the directive makes US complaints about China's state-sponsored hacking "hypocritical," because the US has "participated in offensive cyber operations and widespread hacking."

"We hack everyone everywhere," the intelligence source told The Guardian. "We like to make a distinction between us and the others. But we are in almost every country in the world."

Some of the talking points in the directive were declassified in January, but the emphasis on offensive hacking wasn't made public, nor was the order to create a specific target list.

This third leak comes at a sensitive time, as President Barack Obama prepares to meet Chinese President Xi Jinping in California today. One of the subjects Obama is expected to bring up is Chinese cyber-attacks. Just this morning Obama defended both the widespread collection of call data and the PRISM program that relates to collecting e-mails and other Internet information, saying the government had reached the "right balance" on civil liberties.
